Moana Waialiki is a sea voyaging enthusiast and the only daughter of a chief in a long line of navigators. When her island&#39s fisherman can&#39t catch any fish and the crops fail, she learns that the demigod Maui caused the blight by stealing the heart of the goddess Te Fiti. The only way to heal the island is to persuade Maui to return Te Fiti&#39s heart, so Moana sets off on an epic journey across the Pacific. The film is based on stories from Polynesian mythology.
